Update on last post-she’s flirting with me(?)

I went in this bookstore I’ve never been in bc I wanted to check it out and she was in the back working on her computer, in the moment I wasn’t sure but I got that “tingle” feeling even from 20 feet away. I almost said hi but then left bc I was getting lunch w/ some friends, then I went back up after to buy a book and she came over (I could clearly see it was her now) i was looking at the classics (Holmes, moby dick, 20k leagues, etc.) and she started playing what I can only describe as “eye tag” while “looking” at books, we sort of “chased” each other for about two minutes then we locked eyes and she asked if I was the guy from the restaurant to which I responded yes to, end then we talked for I think around 15 minutes, she asked me about age, where I live, if I work, what I do, and then I asked her some things too. Along the whole interaction she was trying to look like she was looking at books but I don’t even think she looked at the titles half the time and she would just pull them out halfway just to push them back in, also she pulled the same book once or twice. The interaction was cut short when she had a phone call and had to go somewhere, the last thing she said to me was “please don’t die out there, yeah?”. she never told me anything about meeting up or anything and idk what to do? should I go back to the cafe and try and say hi now we’re acquainted? i still don’t know her shifts besides on sunday and I only have one more week (meaning one more Sunda, before I’m out of town for a month. I really got no clue what to do and frank im quite flabbergasted bc this is the first tome any woman has shown even a bit of attraction if it could even be called that.
